Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The SYM-1 was a single board "trainer" computer produced by Synertek circa 1978. Originally called the VIM-1 (Versatile Input Monitor), that name was changed for legal reasons sometime between April and August 1978. The SYM-1 was a competitor to the popular MOS Technology KIM-1 system, with which it was compatible to a large extent. Compared to the KIM-1, enhancements included the ability to run on a single +5 volt power supply, an enhanced monitor ROM, three configurable ROM/EPROM sockets, RAM expandable on-board to 4 kibibytes, an RS-232 serial port, and a "high speed" (185 bytes/second, the KIM-1 supported about 8 bytes/second) audio cassette storage interface. It also featured on-board buffer circuits to ease interfacing to "high voltage or high current" devices.
